Organisers of a new competition are inviting Londoners to re-imagine the city’s urban spaces in a practice known as “commoning”, or reclaiming public spaces to be used by the communities in which they are located.

With London’s open spaces increasingly being developed for profit and managed by private owners (sound familiar in West Hampstead at the moment?) the organisers Theatrum Mundi, a group of urbanists and artists, feel that “the range of activities permitted in urban spaces is becoming increasingly narrow”. How best to reclaim and use these spaces?

Feeling inspired? Perhaps there’s somewhere local, such as the Travis Perkins building on West End Lane, you feel could be used to benefit the local community.

You don’t need to be a professional designer or architect to enter your idea – it’s open to all. Full details can be found on the Urban Commons website, and the closing date is May 1st, so there are still a couple of weeks left to develop your idea.

Ten selected proposals will be awarded £300 toward the implementation of their proposal and will be featured at an exhibition at the LSE as part of the London Festival of Architecture.
